I've got an information, using a dictionary, is very important to get new words. I'd like to be a good learner of English as a second language so I need to know more new words because I'm not the first language speaker. I should try to use a dictionary daily to find new words. It should be an English to English dictionary because I can get more similar meanings with direct way. That's all I'd like to say about benefits of using a dictionary for vocabulary building
